FAQs

1. What makes Megaplast security bags tamper-evident?

Megaplast security bags feature a permanent peel-and-seal adhesive closure designed to show clear, visible signs if someone attempts to open the bag after sealing. This tamper-evident feature is useful for applications where confidentiality, chain of custody and shipment integrity are important, including banking, pharmaceutical logistics and confidential document transport.

2. Can security bags be sequentially numbered or printed with barcodes?

Yes. Megaplast security bags can be custom printed with sequential numbers, barcodes and QR codes. Individual identification helps organisations track each bag, maintain records and improve traceability as items move through internal operations or the wider supply chain.

3. Which industries use tamper-evident security bags?

Security bags are used by organisations that need to protect confidential, valuable or sensitive items. Common applications include banks and financial institutions transporting cash, cheques and documents; pharmaceutical and medical logistics providers handling sensitive shipments; courier companies carrying confidential paperwork; and airport duty-free retailers requiring secure packaging for customer purchases.

4. Can security bags be customised with company branding?

Yes. Megaplast security bags can be customised with company logos, brand colours, sequential numbering, barcodes, QR codes and handling information, subject to the selected specification. Custom printing allows the bags to support both security and traceability while maintaining a consistent brand identity.

5. What sizes are available for security bags?

Megaplast security bags are available in custom sizes to accommodate different contents, including cash, cheques, documents, valuables and other sensitive items. Share the dimensions, capacity and intended use of your shipment with the Megaplast team so they can recommend an appropriate bag size.

6. Are security bags resistant to tampering during transit?

Megaplast security bags are designed to provide protection during transit. The permanent peel-and-seal closure is tamper-evident, while the bag construction is designed to resist moisture, solvents, cutting, freezing and heat. If an attempt is made to interfere with the sealed bag, the adhesive closure is designed to leave a visible indication. Confirm the required resistance level for your application before ordering.

7. Can I write on the surface of a security bag?

Yes. The surface of Megaplast security bags is designed to accept permanent markers, stamps and franking machines. This allows users to add information at the point of dispatch without relying on special equipment or separate pre-printed labels.

8. Do security bags include a document pocket?

Yes. Security bags can be manufactured with a document pocket for paperwork that needs to travel alongside the sealed contents. The bags also feature reinforced seals on three sides, adding another layer of protection against accidental opening and attempted tampering. Confirm the pocket size and seal configuration when specifying your order. Whether you need security bags for cash handling, confidential documents, pharmaceutical logistics, courier services or duty-free retail, Megaplast can help you select a suitable specification. When requesting a quotation, provide the required bag dimensions, contents, closure type, printing details, numbering format, barcode or QR-code requirements, document-pocket requirements and estimated order quantity.
